\({\sigma }_{a}^{2}\), \({\sigma }_{e}^{2}\) and \({h}^{2}\) = additive genetic variance, residual variance and heritability, respectively, of BW. \({\sigma }_{{a}_{d}}^{2}\), \({\sigma }_{{e}_{d}}^{2}\) and \({h}_{d}^{2}\) = additive genetic variance, residual variance and heritability, respectively, of micro-GES of BW on the log-scale. \({\sigma }_{{a}_{d}}^{*}\), \({h}_{d}^{{2}^{{*}}}\) and \({GCV}_{d}\) = additive genetic SD, heritability and genetic coefficient of variation of micro-GES of BW on the measurement scale
